Corsair Professional Series Gold AX1200 Power Supply Review

A Detailed Look

The Corsair Professional Series Gold AX1200 power supply supports the latest ATX12V v2.31 and EPS12V 2.92 standards and is backward compatible with ATX12V 2.2 and ATX12V 2.01. The AX1200 is rated for a combined, continuous output power of up to 1,200 watts at 50°C operating temperature. That’s important as some less reputable manufactures limit their power supply’s advertised capacity by specifying a lower operating temperature (25°C) in the fine print.

The AX1200 PSU incorporates a single +12V output that can deliver up to 100A, which is the full capacity of the unit. The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid.

The Corsair AX1200 power supply enclosure is painted matte black and is 200mm (7.9”) deep. It uses a single 140mm fan on the bottom for cooling, which is the largest standard fan size that will fit into the ATX form factor enclosure. The fan speed is automatically controlled by the internal component temperature (speeds up as the combined load increases). The dual ball bearing Yate Loon Electronics fan (D14BH-12) is a relatively powerful high-speed fan that has the potential to provide excellent airflow and cooling.

The back panel includes a heavy duty On-Off switch and AC receptacle along with an open honeycomb grill that allows the exhaust air to exit the power supply with minimal resistance and turbulence.
